Scalp odor

For example, the yeast Pityrosporum ovale, the major scalp resident, is able to metabolize lipid substrates to 4-hydroxy-aclds which readily undergo ring closure to the volatile and odorous Y lactones. The technique of headspace concentration on Tenax followed by gas chromatographic/mass spectrometric analysis has been used to profile all the volatiles produced by Pityrosporum (Figure 1). These compounds Include isopentanol, benzyl...
